Exporting Graphes - Chart wrapper object and 3rd party

Revit API
1

Hello community, I’m new here and my knowledge of Python is limited so please bear with me :sweat_smile: I’m using versions; pyRevit 4.8, Ironpython 2.7.7, and Cpython 3.8.5.

I aim to manipulate data, produce graphs, and then export possibly as an image/pdf. I have tried two ways, the first “Normal” approach is with builtin ‘PyRevitOutputChart’ and the other with Cpython using 3rd party packages but in both of them I have stumbled on some problems :

  1. pyRevit Graphe: I was able to output the chart within the output window but I can’t find a way to export it. When exporting the window as html the graph was not in it. Seeing the documentation Visualizing Data. I’m not sure where/how i should be inserting commands in Python to export Chart.js like shown by QuickCharts How to download and export Chart.js images (if it is even possible).

  2. With Cpython : My first approach was with Matplotlib but I encountered the same problem as here where the pyparsing from pyRevit was being caught. I ‘forced’ the import from the correct one in my python 3.8 using importlib.util explained here but it gave this error :

CPython Traceback:
ImportError : cannot import name '_api' from 'pyparsing' (C:\Users\Valqu\AppData\Local\Programs\Python\Python38\Lib\site-packages\pyparsing\__init__.py)

From what I searched, it is a double-dependency problem. I tried to understand this post Getting d3.js to work within pyRevit on the forum but honestly, it is way off my league. Then I tried using bokeh and Pygal but both of them when importing gave me identic errors:

CPython Traceback:

What should be my approach to make this work ? Thanks in advance for this amazing tool that I have already done so much :smile:
